McIDAS images of EUMETSAT Meteosat-10 0.75 µm visible channel data (above; click image to play animation) showed a beautiful example of a von Kármán vortex street downwind of Madeira Island on 01 May 2014. Northeasterly winds in the marine boundary layer were perturbed by the topography of the island, whose highest point rises to an elevation of 1,862 m (6,109 ft) above sea level. Note how some of the downwind vortices rotate in a clockwise direction, while other rotate counterclockwise.
